FASTENING DEVICE FOR PUMP CURBS OR FRAMES.

Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed February 24, 1908. Serial No. 417,413.

To all whom it may concern: I

Be it known that I, THouAs T. BAKER, a citizen of the United States,residing at Jonesboro, in the county of Union and State of Illinois,have invented certain new and useful Improvements in Fastening Devicesfor Pump Curbs or Frames; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable otherskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in fastening devices for pumpcurbs or frames.

The object of the invention isto provide a device of this character bymeans of which the frame or curb of a pump may be detachably secured tothe platform, without the use of nails, screws or similar fasteningdevices.

With this and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a vertical sectional viewthrough a pump casing showing the manner of securing the curb to theplatform, Fig. 2 is a similar view taken at right angles to Fig. 1, Fig.3 is a horizontal sectional view of the lower portion of the casing andthe curb, and Fig. 4 is a detail view of the clamping nut.

Referring more particularly to the drawings, 1 denotes the pump curbwhich is adapted to be arranged over the opening 2 in the platform 3 ofthe cistern or well. In the curb 1 is arranged a bail-shaped brace bar4, the lower ends of which are bolted or otherwise secured to the sidesof the curb. In the upper or curved portion of the brace bar 4 is formeda centrally disposed opening 5, through which is adapted to be inserteda clamping bolt 6, the upper end of which is provided with a suitablehandle, which is here shown in the form of an eye 7. The lower portionof the bolt 6 is threaded, and on said threaded portion is arranged aclamping plate 8, said plate having formed therein an enlarged opening9, through which the bolt 6 passes, and by means of which the plate isallowed a certain amount of movement on the bolt to permit the late totilt in one direction or the other, an thus conform to anyirregularities on the under side of the cistern or well platform 3, withwhich the ends of said plate is engaged.

On the threaded lower end of the bolt is adapted to be screwed aclamping nut 10, which when screwed up on the bolt securely clamps theplate against the lower side of the cistern or well platform, andthereby rigidly secures the curb to the upper side of the platform overthe opening therein. The nut 10 is provided on one side with an upwardlyprojecting right angular offset or shoulder 12, which when the nut is inplace against the under side of the plate 8 will engage one edge of theplate and thereby hold the nut against rotation when the clamping bolt 6is screwed downwardly or upwardly through the nut.

To the outer side of the curb, adjacent to its lower end, is secured astop or supporting strip, 14, which is adapted to engage the uppersurface of the well platform when the lower end of the curb is insertedtherein, as shown. By providing the supporting strip, 14, and permittingthe end of the curb to set into the opening, the curb will be supportedand held against lateral movement after being clamped down ashereinbefore described.

In applying the attachment to secure the curb to the platform of acistern or well the bolt 6 is arranged in the brace bar 4 and theclamping plate 8, the nut 10 is then engaged with the lower threaded endof the bolt after which the curb is placed in position over the openingin the platform and the bolt turned to bring the ends of the plate 8beneath the edges of the opening formed in the platform, after which thebolt is turned in the proper direction to draw the nut upwardly thereon,and thus tightly clamp the ends of the plate into engagement with thelower side of the platform, which action will permanently secure thecurb in place without the necessity of employing other fasteningdevices. This arrangement not only provides for securely fastening thecurb to the platform, but also forms a quick means for the attachmentand removal of the curb when desired.

In the upper end of the curb is arranged any suitable water elevatingmechanism, and said curb may be provided with a suitable dischargespout, and a cap for closing the upper end thereof. These parts,however, form no part of the present invention.

Having thus described my invention what I claim as new and desire tosecure by LettersPatent is z 1. In a device of the character described,a pump curb adapted to be inserted into the opening of a well platform,a supporting strip secured to said curb adjacent to its lower end toengage the upper edge of the opening in the well platform whereby saidcurb is supported and held against lateral movement, a brace bar in saidcurb, a clamping bolt engaged with said bar, a clam ing plate on saidbolt having its opposite en s in engagement with the opposite edges ofthe opening in the platform, and a clamping nut on said bolt to engagesaid plate whereby the latter is held in operative engagement with saidedges.

2. In a device of the character described, a pump curb ada ted to beinserted in the opening of a wel platform, means to support the curb insaid opening, a bail-shaped brace bar secured at its lower end to theopposite sides of the curb, a clamping bolt engaged with said bar, aclamping plate having an aperture to receive said bolt and having itsopposite ends in engagement with the opposite edges of the opening inthe platform, and a clamping nut on said bolt to engage said plate.

3. In a device of the character described, a pump curb adapted to beengaged with an opening in the well platform, a supporting strip securedto said curb near its lower end to en age the upper edge of the openingin said glatform whereby the curb is supported and eld against lateralmovement, a bailshaped brace bar having oifset lower ends secured to theopposite sides of said curb, a clamping bolt engaged with said bracebar, means on the upper end of said bolt whereby the same is operated, aclamping plate engaged with the lower end of said bolt, and with thelower edges of the opening in the well platform, a clamping nut on saidbolt to engage said plate, and means to hold said nut against rotation.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
